This section gives an overview of changes since Gramps version 3.3. These changes are also detailed later in this manual. Users of Gramps version 3.3 are encouraged to review this section to be sure to take advantage of these new features.

Before you upgrade

Warning

Creating an archive alone to safeguard your data might not be appropriate before upgrading. In the unlikely event that Gramps 3.4 corrupts your database, it could also corrupt the archive. An export as outlined in this section is recommended.

Before you upgrade, make sure your family tree data is secure. The best way to do this is:

Start Gramps 3.3

Open your family tree

Export the family tree to the gramps xml format or the gramps xml package format (which includes your photographs and other media files associated with your family tree data). Export your tree via menu Family Trees->Backup....

Close this family tree and repeat the above steps for any other family trees you have

After properly safeguarding your data, proceed to install Gramps 3.4. Use your operating system's regular installation process to do this. It is also best to uninstall Gramps 3.3 before installing Gramps 3.4, or make sure you install Gramps 3.4 in a different location.

After you install Gramps 3.4, you can open your existing family trees and continue working. In case of problems (e.g., after a complete system upgrade), use the backup file(s) created above to recreate your family tree(s).

Warning

Once you open a family tree in a newer version of Gramps or using a newer operating system, you generally should not try to open that database using an older version again. As always, the gramps xml format is the format to use for the interchange of your data in such cases. There are tools to repair broken databases, but they are for expert users, so avoid needing them by following the steps above before you upgrade your OS or Gramps.

Under the hood changes

Command Line Interface

Gramps XML file format and database

Exporter do not change records order, making easier to look at differences between versions/revisions.

User classes

Reports and tools have user classes.
These classes provide a means to interact with the user in an abstract way. These classes should be overridden by each respective user interface to provide the appropriate interaction (eg. dialogs for GTK, promts for CLI).
